So, even though I'm using a Windows laptop, rar files don't seem to work with me. Could you perhaps use a zip or exe file instead?
you should install winrar or 7zip, they open rar files easily
I'm gonna be honest, I have no idea where to install either of those.
winrar from https://www.win-rar.com
7zip from https://www.7-zip.org/
id advise 7zip cuz it can also open 7z files
